Title: Fender for cylindrical columns in tidal waters - uses projecting structures to support sliding support points for fender cable
Inventor: LACROIX ROGER
IPC: E02B17/00
Filed: 1981-10-13
Abstract: A tubular steel and cable fender for the legs of offshore structures comprises two support rings one above the other from which projecting structures support a heavy cable fender in the form of a continuous cable which runs in a tubular guide at each support point. The duration of the fender on the leg may be adjusted by lifting cables to allow for tidal variations and at each support point on the rings an anti-friction bearing material is used to facilitate the raising and lowering of the device. Used for the protection of the legs esp. of reinforced concrete offshore structures.

Patent FR-2537186-A1 (FR)
Title: Residence-type module
Inventor: FRANCO JEAN
IPC: E04B1/00
Filed: 1982-12-02
Abstract: Residence module constituted by a polygonal cell whose framework comprises, on the one hand, a pyramidal roof truss formed by rafters leaving from the apex and, on the other hand, a series of posts disposed at each of the corners in order to support this truss. The lower end of each rafters 1 is fixed directly to the upper end of the corresponding post 3, without an intermediate horizontal tie. As regards the posts, they are connected together solely by means of vertical panels 5, each of which constitutes by itself only the corresponding side of the peripheral wall of the cell. The assembly of the elements forming the posts 3 and the rafters 1 is ensured by bolting with intermediate butt plates made from metal and with mutual flush-fitting of the elements to be joined together. The same applies for the assembly of the upper end of the rafters 1 with an upper junction piece 2 provided at the apex of the assembly. This cell can be used as residence, either in isolation or in combination with several identical cells, optionally by adjoining them with an intermediate linkage member permitting two or more cells to be grouped together or a complementary usable surface to be created.

Title: Ion-analyser for mass spectrometer with hyperbolic electrodes - has electrode screens to sort ions, ion-reflecting electrode and micro-channel stack in front of detector
Inventor: SHERETOV ERNST PANTELEIMONOVIC
IPC: H01J49/42
Filed: 1983-02-15
Abstract: The mass-spectrometer has symmetrical hyperbolic electrodes (5,6) and an external electron gun (1). Electrons (2) enter the working space and ions to be analysed pass through an opening (10) of diameter 19 mm. in one of the electrodes. The sorted ions are accelerated by a high potential on a cylindrical electrode (13) in the analyser, passing through a 2 cm hole (12) in a diaphragm (11). A conical ion reflector (16), at a potential of around 200 volts, sends the ions into a stack of micro-channels (18) which further screen the ions and slow them down. A detector (15) is situated at the end of the micro-channels. The reflector electrode (16) spreads the ions uniformly over the micro-channel stack and increases the speed of counting in the collector (17). The working surface of the micro-channel stack is positioned in such a way that the background radiation, generated in the ionisation zone, has a negligible effect on the counter. The sensitivity and resolution of the spectrometer are thus enhanced.
